Device for moving transverse beams for transporting work pieces to be galvanized along support rails

Abstract

A device for moving transverse beams and workpieces suspended therefrom along a support rail in the longitudinal direction of the support rail. Each one of the transverse beams is connected by lifting devices, for lowering and lifting the workpieces connected to the transverse beam into and out of the zinc bath, to transport carriages riding on the support rail. The transverse beams have a vertically movable doctor blade arrangement at the leading end for removing contaminants from the surface of the zinc bath.

What is claimed is: 
     
       1. A device for moving workpieces to and from a zinc bath and lifting and lowering the workpieces out of and into the zinc bath, wherein said device comprises: transport carriages riding on a support rail in a transport direction and having lifting devices;   transverse beams from which the workpieces are suspended;   said transverse beams connected by said lifting devices to said transport carriages;   wherein each one of said transverse beams comprises a vertically movable doctor blade arrangement at a leading end thereof in said transport direction along the support rail for removing contaminants from surface of the zinc bath.   
     
     
       2. A device according to claim 1, further comprising means for automatically lowering said doctor blade arrangement to the surface of the zinc bath when said transverse beam reaches the zinc bath. 
     
     
       3. A device according to claim 1, wherein said doctor blade arrangement comprises a vertically movable, vertically extending shaft connected to said leading end of said transverse beam and further comprises a doctor blade matching a width of the zinc bath, wherein said doctor blade is connected to an end of said shaft facing the zinc bath. 
     
     
       4. A device according to claim 3, wherein said shaft is a toothed rack driven by a gear wheel. 
     
     
       5. A device according to claim 3, wherein said doctor blade is a rectangular, flat member comprised of a rigid material.
